I want to develop a magnifier window in my already existing graph view.
The graph contains symbols of some component , sometimes the symbols are so large in quantity so i cant view them in a simple scroll, and if i want to see them all at a same time i have to zoom out the window,by doing that the size of symbols become so small that i cant view than easily.
To view them(symbols) i want to develop a magnifier window, so it will zoom that part where i want to see the component.
Similar example (Working example)
In adobe reader we have a thumbnail view of all pages on left side, here we have a magnifier window which we can re-size also.
